New polymer system cures by UV light and/or heat

12 March 2008

Master Bond has introduced a new one component, optically clear, non-yellowing UV and/or heat curable polymer system called UV15-7DC. This high performance system is designed for bonding, sealing and coating applications. It is 100% reactive and does not contain any solvents or other volatiles. UV15-7DC is not inhibited by air and exhibits a desirably fast UV cure at ambient temperatures. Typical cure times range from five seconds to 2-3 minutes depending upon the wave length, intensity of the UV light and the thickness being cured. Typical heat curing schedules are 10-30 minutes at 250-260°F. Heat curing is recommended for use in applications with “shadowed out areas”.

Master Bond UV15-7DC is easy to use and has a low viscosity. It has outstanding durability and toughness, thermal shock resistance, and excellent adhesion to many different substrates. These substrates include glass, metals, plastics, polyester films and polycarbonates. It has a Shore D hardness of >70 and an elongation of 65-75%. Its tensile strength is 5,460 psi.

Master Bond UV15-7DC is available in pint, quart, gallon and five gallon containers. For ease of application, it also is available in syringe applicators.
